# Be extra careful when you edit this file, because it affects AOTInductor ABI compatibility. See
# https://github.com/pytorch/pytorch/blob/7e86a7c0155295539996e0cf422883571126073e/torchgen/gen.py#L2424-L2436
# for details.
#
# The inductor_fallback_ops list is based on the fallback ops from torch/_inductor/lowering.py.
#
# Generally speaking, it is ok to add a new op to the list, but you need to run
# `python torchgen/gen.py --update-aoti-c-shim` in order to regenerate C shim header files.
# But it is NOT ok to remove an existing fallback op from the list, since that will break
# some existing AOTInductor-compiled models.
#
# A fallback op version defaults to 1. If you want to extend an existing fallback op by adding
# a new argument with a default value, while it is fine in the Python world, it will be BC-breaking
# when generating C shim. Thus you need to bump up the version number of that fallback op by
# updating the entry in the inductor_fallback_ops list, adding a new version number with a list
# of new arguments, and then run `python torchgen/gen.py --update-aoti-c-shim` to regenerate.
